Hi, Tom here and welcome to this week
Circle Line Art School video: How to Draw a
House in cross-section in one-point
perspective, the first step in this
drawing is to draw a horizontal line in
the middle of your page, next draw a
cross in the center of this line for the
vanishing point, all diagonal lines in this
drawing will end up at this vanishing
point, now draw a vertical line on the
left of the vanishing point
and then another vertical line over to
the right of the vanishing point,
next or two more horizontal lines to
make a rectangle and this will be the
first room,
we can add a double line around
rectangle to show the thickness of the
walls in this cross-sectional drawing,
a cross-sectional drawing is like the
house has been cut in half and we can
see inside the rooms of the half cut
house, but also we can see the thickness
of the walls where it's being cut in
half next,
next, draw four diagonal lines from the corners of your rectangle to the
vanishing point in the center of the drawing,
we can already see, hopefully, that the
walls, the sidewalls, are appearing in
this one point perspective drawing,
now we can add another diagonal to make a
hallway coming towards us
and now we can draw another smaller
rectangle using the diagonal line on the
right, so that we know how high this
rectangle will be, so that the diagonal
line on the right represents the line
between the ceiling and the wall on the
right, so we don't want the vertical line
to go above the diagonal line, on the left
we can add a short diagonal line to make
this new rectangle into a
three-dimensional shape, now I'm going to add
an open doorway
and then add another rectangle here for
the back wall of the hallway, otherwise
it would look endless, going all the way
to the vanishing point...
next in the doorway here we can add some
simple steps, some rectangular shapes
that need to get shorter as they go up,
they get short on the right, we could add
some horizontal lines along this hallway
with bigger gaps as the lines get closer
to us, this will help create a sense of
space in our drawing, I'll add some more
lines on the right here, again starting
close together and then getting further
apart as they get closer to us...
now we can erase some of the guidelines
that we no longer need in this drawing,
I will speed up the drawing for a moment here, while I go over the lines
that we've drawn in pencil with a
thin black pen,
any of the pencil lines at this stage,
if I need to change them, I can just
correct them as I go over them will the
pen,
next I want to draw some steps, but these
I want to make them
in front of the cross-section,
so first I will draw
a diagonal line here, which is at the same
distance that the cross section is at,
and then I just need to add, we can add a
zigzag line, to create the steps on this
diagonal line which is the same distance
as the cross section of the room,
we can draw a vertical line here and
then add a diagonal line from our
vanishing point to make this a
three-dimensional shape, to make it look
like three-dimensional shape, then if we
draw another diagonal line on the left
we have another hallway, below our first
hallway, that we have already drawn, so
sort of one hallway on top of another
hallway, showing the two floors of the
building that we've drawn so far,
again we can draw a rectangle at the back for
the back wall of the hallway because,
again, we don't want it to look as if it
goes away endlessly
into the distance, now we can add a
series of diagonal lines from the vanishing
point going to the corners of each of
the zigzags of the steps that we drew earlier,
and we can continue these diagonal lines towards us, coming
towards us, so we are creating steps to
come right out towards us, further than
the cross-section of the drawing, I can
extend the hallway at the front here too,
now I will speed up the drawing again for a
little while, while I just go over the
pencil lines with a black felt-tip pen,
next on the left of the first vertical
line that we drew we can draw three
sides of a rectangle,
and then add a wall on the left,
a vertical line here, now to make this open
rectangle into an interior swimming pool
we just need to add a slightly wavy
horizontal line at the top along here,
again we can make the swimming pool look
three-dimensional by using our vanishing
point to find the diagonal lines to give
these shapes that we've already drawn a
depth, using 1-point perspective, I will
draw a long step on the left along here,
we can find the top of the wall on the
left and the line up to it, with the
height of the first room that we drew,
sort of reading across from there...
again I'll go over all the pencil lines
that I've drawn with the pen,
now I want to add some distorted
wavy lines in the swimming pool,
horizontal and vertical lines, to give
the impression of tiles seen through
water,
next on the right here I want to extend
this line to make an overhang, we can
give this the same thickness, and create
depth, by adding a diagonal line from the
vanishing point,
now we can add some thin columns
to support this overhang, the first
column needs to go all the way down to
the ground and then if we draw a
diagonal line from the base line of the
ground, that will show us where all the
other columns need to finish at,
so this diagonal line, going from the vanishing
point to the base of the first column
will show us where all the other columns
need to rest upon, now there's some space
at the top of this drawing, so I'll add
another storey to the building and for
that, we just need to draw a horizontal line
for the height of the storey, but I'll
make this storey of the building behind
the cross-section of the rooms, so that
it's not cut in half as it were, so the
steps that we drew earlier on, are in front
of the cross-section and this new storey
for the top of the building is behind
the cross section,
now I'm just going to go over
of the lines with this black pen,
I'll add more lines in the pool, but I'll make
sure that they're all broken lines, I
don't want these lines too solid, because
we're looking through water, that want to
give the impression of the water could
be moving and that it's not the same as
the structure, the architectural structure,
of a solid wall and I'll add a dotted
line for the horizon, in this drawing I use
a 4B pencil, a black pen, a gray
marker pen and some colored pencils, that
mix with watercolor to blend,
if you want to add color to your drawing,
any color medium would work perfectly well,
So speeding up this video I will use the grey marker pen to add some tone to
the walls of the building, starting with
all the walls on the right hand side,
just giving them a gray tone,
I'll add a dark tone to all of the
ceilings as well, next, time to use these
watercolor pencils, to add some color to
the pool, keeping quite a lot of white
visible, so if you use color felt-tip pens,
they would work very well for this as well
and now just adding some water to blend
these colors that I put in this area,
I will add a graded blue
to the sky, I hope you liked this video
and find it useful for your own drawings.
